The Difference Between a Brain and a Computer
The difference between a brain and a computer can be expressed in a single word ;complexity.
The large mammalican brain is the most complicated thing ,for its size,known to us .The human brain weighs three pounds ,but in that three pounds are ten billions of cell are interconnected in a vastly complicated net work that we can`t begin to unravel as yet .
Even the most complicated comprter man has yet built can`t compare in intricacy with the brain ,computer switches and components number in the thousands rather than inthe billions .What`s more,the computer switch is just an on -off device,whereas the brain cell is itself possessed of a tremendously complex inner sturcture.
Can a computer think ?That depends on what you mean by "think".If solving a mathematical problem is "thinking,"hen a computer can "think"and do so much faster than a man .Of course,most mathematical problems can be solved quite mechanically by repeating certain straight-forward processes over and over again.Even the simple computers of today can be geared for that.


mammalian adj. 哺乳动物的
intricacy n. 复杂,错综
